What Is GLM 5 AI?
GLM 5 AI is a fifth-generation frontier large language model featuring 745B total parameters, Mixture-of-Experts architecture with 44B activated parameters, and 128K context window — delivering open-source SOTA performance across reasoning, coding, and agentic tasks.
GLM 5 AI Architecture: MoE with 745B Parameters
GLM 5 AI uses a Transformer decoder with Mixture-of-Experts (MoE) structure — 78 layers, 256 experts per layer with 8 activated, yielding ~44B active parameters at 5.9% sparsity. The first three layers are dense; subsequent layers use DeepSeek-style Sparse Attention (DSA).
GLM 5 AI Advanced Reasoning & Coding
GLM 5 AI achieves state-of-the-art scores on MMLU, BBH, HumanEval, and AgentBench. Its agentic reasoning pipeline and code generation capabilities compete with Claude Opus 4.5 and GPT-class models — making it the open-source coding and agent SOTA.
GLM 5 AI 128K Context & Multi-Language Support
GLM 5 AI supports a 128K token context window for long-document understanding, multi-turn dialogue, and complex agent workflows. Native support for English, Chinese, and 15+ additional languages with leading multilingual performance.
GLM 5 AI Multi-Token Prediction (MTP)
GLM 5 AI employs Multi-Token Prediction for faster inference — predicting multiple tokens per forward pass, reducing latency while maintaining output quality. Combined with DSA, this delivers 2x throughput over traditional autoregressive decoding.
GLM 5 Key Features and Capabilities
GLM 5 delivers frontier-level performance across reasoning, coding, creative writing, and agentic AI — rivaling the best proprietary models.
Advanced Reasoning
GLM 5 excels at multi-step logical reasoning, mathematical problem-solving, and complex analytical tasks with chain-of-thought capability.
Agentic AI Workflows
GLM 5 powers autonomous agent pipelines — tool use, function calling, multi-turn planning, and self-correction for complex real-world tasks.
Code Generation
State-of-the-art coding performance on HumanEval and BigCodeBench. GLM 5 generates, debugs, and refactors code across 50+ programming languages.
Creative Writing
GLM 5 produces high-quality long-form content, marketing copy, technical documentation, and creative fiction with nuanced style control.
128K Context Window
Process entire codebases, research papers, and legal documents in a single prompt. GLM 5's 128K context enables true long-document understanding.
Image Generation
GLM 5 ecosystem includes Seedream 5.0 for photorealistic 2K image generation — text-to-image, image editing, and multi-subject composition.
